FEED-WATER FILTER.

To att 'whom 'it may concern:

Be it known that I, Itonnn'r C. MONTEAGLE, of l. inchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Feed-Tater Filters, of which the following is a specification.

This invention relates to that class of feed water filters in which a series of perforated pipes are provided within a casing and covered with a filtering material, the feed water being conducted through said filtering material and into and through said pipes as it passes to the boiler. In many instances, as on ship-board, it is desirable that these filters occupy as little space as possible, and that the wei ht thereof be reduced to a minimum, an it is further desirable that as much filtering surface as possible be provided or the space which is occupied.

The primar object of my invention is to provide a fee( water filter' of the above de scribed character, in which the perforated filtering pipes shall be soconstrncted and arranged that a maximum surface for filtration shall be provided in a minimum space, and further to provide an arrangement whereby the capacity of the device may be indefinitely increased without detracting from the eompactness with which the pipes may be arranged. As these perforated filtering pipes are arranged in a cylindrical casing of considerable length, and, as it is necessary to remove said pipes at intervals for the purpose of renewing or cleaning the filtering material which covers 'much difficulty has been exin placing the pipes back in posiperienced a further object tion, and in this connection,

of my invention is to provide means wherebyv said pipes may be readily replaced.

For a complete understanding of my invention and the means which I'employ in accomplishing saidV objects, reference is made to the accompanying drawing, in which,

Figure l is a longitudinal sectional view of my apparatus taken on the line 1-1 of F ig. 3. Fig. 2 is a detail view of the end supporting plate. Fig. 3 is a sectional view on the line 3-3 of Fig. 1. Fig-4 is a similar sectional View illustrating a modification of my invention. Y

As shown in the drawing, a cylindrical casing a is provided, said casing having an inlet port a and a discharge port a2, and said .passages a and a2 beinv connected to a fourway valve b by means of which tliefiow Specication of Letters Patent. Application led November 2, 1908. Serial No. 460,569.

Patented Aug. 10, 1909.

I to the boiler may be directed through the y casing or may be conducted directly to the boiler.

The General construction above described is Well Imown in the art.

According to my invention I provide a parallel series of pipes c, which are cquilaterally triangular in cross section, as best shown in Fig.l 3, the portions between the sides being rounded, and said pipes being covered with filtering material d, in a manner which will be readily understood. Said pipesl c are so i arranged with reference to the cylindrical l casing in which they are contained that the longitudinal center line of each pipe will intersect the vertices of a liexagon, the center of which is in the longitudinal center line of the casing, and further, so that two of the sides of each pipe extend nearly radially, with relation to the center of the casing, and approximately parallel to the corresponding sides of the next adjacent. pipe, the third side extending approximately circinnt'ercntially. By this arrangement the pipes are conipactly held, and the area of the filtering surface which 'is provided within a cylindrical casing of a certain diameter is much greater than the area ot the surface which would beprovided with any other arrangement of twhich I am aware.

The end wall a3 of the filter chamber is provided with passa es a, in which the ends of pipes c are fitte and said passages are provided with tapering seats at their inner ends, against .which correspondingly shaped ribs c on said pipes c, are adapted to seat, so that, when said pipes are in position and are yforced against said seats, a tight connection will be made between the pipes and the casing.' The opposite ends of said pipes from their seating ends c are closed and are provided with integral, ta erin centering projections c2 which are a apte ,to fit into a eorrespondingseries of apertures c formed in a circular centering late e, which is fitted in the casing, and held) in posit/ion by, a removable capl f, the latter being clamped,-` by screws or other suitable means, against the end'of .the easing. Spring Washers g are provided between the shoulders formed at the base .ofsaid projection c2 and the plate e so thatwhensaid cap f is secured in place the tapered `ends c of the pipes will be clamped against their respective seats. Said plate e is provided with a central aperture e2, to -permit the water pressure at each side `agonally-shaped projection a5, which is formed on the wal-l a3 with its center in the center line of the casing. With this arrangeincnt the curved outer edges of said flanges are placed against the wall of the casing, as

the pipes are slid into the casing, and hold.

said pipes in suoli position that their ends maybe readily inserted in the apertures at. The projection a5 also materially aids `in directing the pipes into position, particu lai-ly those inv the upper portion of the casing. rlhe side edges of the Hanges of a pipe which has'been placed in position also assist iii directing adjacent pipes into osition.

In Fig. 4: a somewhat modified orm of my invention is shown, in which a series of six triangular pipes h are arranged in the same manner as the pipes c, before described, and, to utilize the space between said pipes a, hexagonal pipe z' may be centrally 'disposed with relation thereto. A further-seriesof triangular pipes j are radially arranged with relation to the pipes h, one of the sides of each pipe y' bein arranged parallel to the circumferential si e of the corresponding inner pipe it. Aseries of triangular'pipes lc are arranged in' pairs between each pair of lpipes j, yone side of"each pipe In of a pair parallel to one side of the adjacent pipel j and another side thereof being arallellto a lside of the other pi e of the pair, third side of each exten ing approximately 'ciI-,

cumferentially. A series of hexagonal pipes m mayA also be arranged centrally v'of each group of pipes, comprising two of each `of v the pipes it, y, and 7s, and the s ace within the casing be thus completely uti ized.

Having thus described my invention, what I clain'ril asnew and desire to secure by Letters Patent is 1. A ltercomprising a cylindrical casing, a circularly arranged series of perforated, triangularly shaped pipes mounted'in parallelism, each pipe being so arranged that two ofits sides extend approximately radially and' the third circumferentially with relation to the casing, and'means for causing the liquid to be filtered to pass through said perforations, substantially as described.
